This invention relates to certain improvements in chucks or journals for supporting the web rolls in rinting machines. 3,

A particular j ect of the present invention is to provide a chuck of improved construction provided with a supporting part or member which can be moved into and out of operative relation with the spindleof a web roll, and which can be locked in operative posi- 1 tion so as to prevent the accidental displacement of the roll when unwinding.

A further object of thleinvention is to produces. chuck of few pa "s and of simple arm rangement which can be readily and quickly moved into and out of operative relation with the web roll, and in which a simple means is provided for efiecting an adjustment'of the parts. I

With these an 9 1y referred'to in view, the invention consists in certain novel parts, arrangements and combinations which will'be described in connection with the accompan ing drawings and the novel features pointe out in the claims 5 hereunto appended.

In these drawings,.

Figure 1 is a side view, artly broken away and partly in section, 0 the improved chucks, the parts being shown inroll holding of one of the chucks shown in Fig. 1, the view being taken looking in the direction of arrow.

2 of that figure, and p Figure 3 1s a sectional view taken on the line 3-3 of Fig. 2, showing the adjusting devices and the p of a roll.

Referring now to these drawings, there is shown a web roll R, which is rovided with the usual core 1 shown in dotted lines, the core bein an iron pipe or the like, on which the roll is wound. This roll is supported at each end by one of the improved chucks. These chucks are duplicates of each other, one being provided for each end of the rolls. While the specific construction of these chucks may be somewhat varied, they yvill include a part which may be moved to enter the roll spindle (1 other objects not specifical-- arts in position when moved clear and form a bearing for the roll so that the,

roll may freely rotate in the machine, and the chuck will include a means for looking I the movable part in its adjusted position in the roll core.

In the particular construction illustrated, gm chuck is supported in suitable framin and will include a two part bloclq3, 3', which has a sliding movement, as a whole in a recess 4 in the frame 2, the two parts of the block also having a relative sliding movement, hereinafter referred to. The block 3' carries at its front end a journal for the roll which consists fa cone-shaped member 5 which is secure to a projection" 6 formed on the end of the block by a collar 7 and a screw 8. The cone-bearing 5 fits over a sleeve 9 whichhas ball-bearing engagement in a recess 10 formed in the face of the block, and is also provided with roller-bearing engagement betweenthe sleeve and the pro'ection 6 on the block, before referred to. T us the bearing 5 has a very free rotation in the block.

Means are provided for effecting a longi tudinal movement of this block to operatively position the .cone-b'earingin the core of the roll. While these means may be somewhat varied, as shown, the block- 3' is provided on one face with'a rack 12 with which engages a pinion 13 carried on a rock shaft 14 su'pported in the framing. Thisrock shaft at its outer end has secured thereto a hub 15 to which is secured an o ratin arm 16 provided with a handle 17. y' whic the arm may be rotated. It willbe seen by the rota .tion of the'handle 17 the rack will be operatedto move the cone-bearing from the position shown in Fig. 3, where it is clear of the roll" core, to that shown in Fig.1, where it engages thecore. 4

In the best constructions, means are .providedfor locking the parts in ad usted pos1-. -tion. While these means may be ofvariops' characters, in the particular construction 11- lustrated, there is provided a -l .pin 18 provided with a flanged-head 19. e arm- 16 is provided with a central hub 20 to'rec'eive the locking and a spring 21 surrounding the pin. e other end .of this pin.18drops in'a recess 20' ina rojection on the,,fr'aming, when the arm 16 1s rotated 7 to advance the core, and holds the parts in locked position. This pin isoperated to release the arm by the operation of the handle 17.. To effect this, this handle is a two part handle, the lower part of whichis stationary, being supported in a hub 22 carried on the lower part of the arm 16. The upper part of this handle 23 is pivoted on a pin 24 secured in the outer end of the hub and carries a yoke 25 engaging the locking pin 18. By

depressing the handle 23, the pin is moved to the right and the arm can then beswung. If desired, a stop 26 may be provided for stopping the arm. 7

In the best constructions, means are provided for adjusting the movement of the block. While these means may be somewhat varied, in the part cular construction shown, the two parts of the'block 3, 3 are held together so as to have a relative sliding engagement by a key 27. The block 3' is provided with a recess 28 which receives a projection 29 extending inwardly from an adjusting wheel 30. The projection 29 is provided with an annular groove 31 in which seats a two part collar 32, this collar being secured to part 3 of the blocks by screws 30, the wheel 30 thus being secured to the block 3. The

projection 29 is provided with a threaded' opening 33 which receives one end of a screw 34, the other end of the screw 34 being tapped into the block 3', this screw being provided with a collar 35. By turning the handwheel 30, the screw 34 will efl'ect an adjusting movement of the block 3 relatively to the block 3,

, the block sliding in the recess 28. This adj ustment is provided to efl'ect a movement of one of the cones independent of the-movement given the cone by the pinion 13 so that the cone may be so positioned relatively'to the roll as to enter the roll core the required distance. This construction is needed and is therefore shown as used with only one of the chucks. v

The block 3 is held against rotation in any suitable manner so as to insure engagement of the rack and pinion, as by a set screw 36.

With the construction shown and described, it will be seen that a very simple and I eflicient chuck for-holding a web roll has been 'provided, one of few parts which is very quickly and easily manipulated, and one in which the parts are so arranged as to be automatically locked, it being necessary to operate the locking means only when it is desired to release the chucks.

While the invention has been shown and described in its preferred form, it willbe understood that various changes may be made in the specific arrangement ofthe parts and that the invention is not to be restricted to the construction and arrangement shown and described. What claim is:

1. In a chuck mechanism for supporting a Web roll, the combination with framing of inner and outer telescoping blocks having a sliding movement in 'theframing and non- Y rotatable with respect to each other, a core engaging member carried by one of the blocks, a rack carried by the other of the blocks, a gear engaging the rack, an operating arm for operating the gear, and means for lockmg the arm in core engaglng position.

2. In a-chuck mechanism for supporting a web roll, the combination with training, of a block having a sidewise movement in the framing, a cone-journal carried by the block a gear for operating the rack, an inner second block having a sidewise movement in the first block and-carrying a cone-journal for engagement with the core of a roll, and means concentricwith the inner block for efiectinga movement of the inner block with respect to the roll core and independent of the gear for adjusting the sidewise position of the cone.

4. In a chuck mechanism for supporting a web roll, the combination with framing, of an outer block having a sidewise movement in the framing, a rack carried by the block, a gear for operating the rack, an inner second block having a sidewise movement in the first block and. carrying'a cone-journal for engagement with the core of .a roll, a screw secured in the inner block, and means for operating the" screw to effect an adjusting movement of aid inner block independently of the outer block and relatively to the core of the roll.
